Specification of Letters Patent.

Patented Dec. 5, 1.916.l

Application led September 30, 1915. Serial No. 53,392.

To all 'uvJLom it may concern Be it known that I, ROBERT C. RUSSELL, a v

i citizen of the United States, and a. resident of Pittsburgh, inthecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Indexes; and I do hereby declare thefollowing to be a. Jr'ull, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in indexesr-one object of theinvention being io so construct and arrange an index as to facilitatethe compact grouping of names in a manner to permit the ready locatingof any' name without necessity of searching through a great number ofnames.

A further object is to provide a'simple in- -dex whereby" the names maybe grouped without depending solely upon given names and withoutrecourse to vowels in the namesh Y With these and other objects in View,the

" invention cons'sts in certain novel Jfeatures of constructie andcombinations and arrangements of. features as hereinafter set forth .andpointed out in the claims.

improvements may be embodied in book form of the loose leaf type, orthey may be applied to a card index.

:In the accompanying drawings; 'Figure 1 isa view of a loose leaf bookshowing an embodiment of my invention; Fig'. 2 is a' ions according tokey letters comprising but f tive consonants, namely: L, M ,jN, R, T 1`,-and combinations of these consonants. There are, however,comparatively few names which could not 'proper-ly be indexed under anyof these sub-divisions,

" and these may be indexed under a Miscellaneous heading. Names ofcorporations may be indexed separately according to their initialletter.

I propose to make what may be termed l a double grouping of names,"either in a singie book or single set ot cards or in a number of booksor several sets of cards. For mstance, one book or set 'of cards may bedevoted to all names having the same initial letter, or a single book orset of cards may be employed for names having several differcnt initialletters or all the letters A.of the alphabet as initial letters. In Fig.l, I have shown a book arrangedfor names h'a-ving initial letters, R, S,T, U V, and W,-each group of pages being' separated by a spacer l, andthe pagesot the book are numbered consecutively.

In Fig. 1, the leaves of the book are shown as being ruled anddesignated to ire-V ceive the names of grantorsand grantees and thevolume and page on which deeds are recorded, as well also as to dates onwhich such records were made. In the pres ent instance, my improvedvindex applies to the naines yof grantors only. On each leaf of the book(and also on the spacers 1 if desired) twokev tables 2 and 3 areprinted.

'The key table Q contains all the letters of name haring the initialletter S will be entered in the S book or group andWB in the B book orgroup,` etc., `but aside Afrom -this general grouping, the initialletter is disregarded andv the' name will be entered in accordance withthe key letterl or letters which first appear inI the name after theinitial letter. fSiegel or Sholesor Sloss would be entered in the S bookvor'groiip according to the key letter L.

f [n order to locate any name in the book, the number of the initialletter is ascer-l tained from the key table 2, and the number of the keyletter in the name is ascertained from the key table 3 and suiiixed tothe number of the initial letter, the result being the number of theleaf of the book on which the name may be found. For example, theinitial letter S in the name Siegel is 19 and the key .letter lappearing in this name is 17h Thus the name Siegal is tou'ud on page1.91." To further illustrate,

lu-'name Vermillion may b'e selected for The letter V is number 22 andseu rch. the Iii-st key letter' appearing after the ini- The key table 3contains1 For instance the name tial letter is R l which is numbered lin the ke \r tahle 3. Thus the naine Vermillion should he found on page4224-.

Then a book eontains several groups ol` initial letter naines. eachgroup unav he provided with a tab 4 having; the initial letter and itanumber, thereon, as indieiited -in Fig. l,

When luy improvements are applied to 'ard instead of leaves of a hookeach initial letter group of cards is sulidivided into key lettergroups. and the. first fair 5 of theinitial letter group rua.)7 he of adilferent color troni that ot' the guideI cards (l of the key letterImoulin-while the rards 'T of vai-1| key letter group may lie ot' a eolorvon tratin;r with guide eards. The guide ral-d ol each initial letter`group is provided with a tali H on which the initial letter and thenulnlier eorrespondiuit thereto. are printed. Thus. in Figr. 2. the talion the initial letter guide wird has printed thereoir the letter H and.its nulnher. lli. The guide eard 3 also hais printed tlwreon. the tu'okei-"tables 2 and 23, and these taliles mayv also he printed on theraide cards l. ilE desired. 'llie soveral guide en rda l are providedwith tahs 9. on which the ke)7 letters and muuhers ot' the k e table 3are printed. successively, The cards 7 ot' each ke).7 lettei vroup arenotched in Snell manner to expone names on several overlying, eax-dsas'. illustrated in Fig. il.

ln #searching t'or a naine in anyr main group. the searrher may selectthe initial letter uuniher; then appl \1 thereto the key' letter numberas previously exj'ilained. and

Athen read the initial letter number with the key letter `number on theIgroup of cards. For example. to find the naine Shipman, or Simon, orSjvinen or Symons, the Searcher may add to the initial letter number1.9. the key letter number 2.-tlius reading 1.92 and by thus Combiningthe numbers oil-,the guideeards 5 and4 (3. the cards with the 'nainesiuentionedwill be at once found.

It' desired, the initial ltters andkey letters muy be omitted from .theguide' cards. and the index operated in 'accordance with the numbers asinililrated on the Mio kei7 tables.
